OK, don't go hiding under a chair or start banging your head against the wall, I know what kind of oil I want to use in my car.
This summer I plan to do my first oil change on my Eldorado. I have picked up the FSMs from eBay and it doesn't seem too complicated. But I do have a couple of questions:
1. I've been told that the oil filter is hard to remove and that an old-fashioned "sling type" removal tool would not suffice. What should I get and where can I find it?
2. The FSM states that I should fill the oil filter with oil before installation. This is where I'm concerned about screwing up. How much oil do I put in there and do I fill it in the center hole or in the surrounding holes?
I was just curious, because I don't want to ruin my car but I'd feel a lot better doing some things myself. So I figure, I may as well learn while I'm able. Your help (and any tips) is much appreciated!
I don't know why the Eldo would be different but my DTS is very easy access to the filter like most cars. If it's difficult to access then a can type wrench will work best. Fits around the bottom of the filter and attaches to a ratchet.
It has been a best practice to pre fill the oil filter forever. Just dump the oil in there slowly, it will fill up quick then settle down. Normally they hold about 3/4 of a quart. It doesn't have to be all the way full, you're just trying to prevent oil delay to the engine.
If the filter is empty at start-up then you're running with 0 oil pressure to the engine until the filter is primed. Pre filling prevents this and delivers oil to the engine right away, as it should
Except mine is nicer, deeper and fits a couple different size filters.
It works perfectly on the delco PF61.
You certainly can fill the filter, just put the oil in the center slowly until it won't take any more. The oil will saturate the filter and drop. No it is not necessary but you certainly are welcome to do it if you want.
The biggest problem with getting a filter off is the moron who put it on before you.
As soon as the seal on the filter kisses the block, you only need turn it 3/4 of another turn.
Don't install the filter with a filter wrench or overtighten it by hand.
All you have to do is snug up the seal, it doesn't hold the engine together!
I have gone through some serious nightmares due to morons overtightening filters!
They have a picture on the side of the filter that shows you how to install it.
It used to be plain English... as I described above.
Has anyone ever read the label on an oil filter?
Now it has an icon and a fraction, so you have to think a little bit when you look at it.
At least the Delco filter is that way.
I am not sure that is the specific one for the 61.
This is the EXACT one I have, it is available online through Snap-on.
It is the best one for GM filters I have seen on the market.
It has the best fit of any of the other ones I have tried and it works like a charm.
I've always only used hand-strength on mine, actually all 4 of my vehicles. Fortunately I can reach them good enough to get a grip and am able to remove and replace with peace of mind. Always lubed the seal but never pre-filled.. maybe nowI will.
90% of engine wear happens at startup when there's no oil pressure. Imagine dragging that out to 20 seconds while the oil filter fills up.
As long as the oil pressure light isn't on, the engine has sufficient pressure.
I've never pre-filled a filter. The light doesn't stay on in any of my vehicles for longer than maybe 1 second after the engine starts. Even with a dry filter, the pressure is built almost immediately.
